When repairing, you may occasionally find yourself having to drill through the glass. This surgery is feasible, but it necessitates specific precautions, the use of the proper tools, and the appropriate technique. As a result, we recommend that you learn everything you need to know in order to effectively drill your glass without damaging it or harming yourself.
When to Drill Glass?
You may be required to drill into glass in a variety of situations. Although this operation may appear complex or perhaps impossible at first appearance, it is actually within everyone’s reach. Here are several scenarios in which you might need to punch holes in glass:
- To design ornamental accents
- To personalize objects
- To make a lamp out of a bottle
- When your DIY projects, such as electrifying a shop window or installing an aerator on a window, etc.
Tools Needed for Drilling Glass
The technique for drilling through glass differs based on its thickness. You should be aware that the thickness of the glass is typically between 3 and 8 mm.
To drill glass, you’ll need to rest against a flat surface, such as a piece of plywood or chipboard, a workbench, or an office table. The most crucial thing is that you are at ease during this piercing procedure.
You’ll Need:
- A variable-speed drill
- A diamond bit or a tungsten carbide bit
- For larger holes, a circular suction cup glass cutter
- A marker to mark marks
- A tape measure
- Cork or rubber for a flexible support
- A spray bottle filled with water to spray the bit while you drill
- Finally, what you need to protect yourself: gloves, goggles, and well-covering clothing.
The size of the bit you need to use will be determined by the diameter of the hole you wish to create.
Glass Drilling
To proceed with drilling the glass without breaking it, follow the steps outlined below after putting on the essential safety gear. Be in mind that glass is a sharp material, and fragments can be harmful to the eyes.
Drill Small Diameter Holes
- Place the glass to be drilled on a flat, stable surface.
- Once the glass is installed, a barrier must be placed between the glass and the flat surface. It could be rubber, cork, or something else.
- Trace the location to drill on your glass with a marker.
- Wet the glass and the drill bit you’ll be using with the water spray bottle before you begin drilling. It will be useful if you detect that the surface is beginning to heat up.
- Begin drilling on the previously sketched mark(s) without pressing too hard or too quickly. Remember to moisten on a regular basis and apply consistent pressure.
- Pause halfway through the thickness and flip the glass over to begin drilling on the opposite side and reconnect the hole you started on the opposite side. You can now adjust the speed of your drill to 400 RPM, but not any higher. You will avoid cracking the glass this way.
Drill Large Diameter Holes
If you need to drill a large diameter hole, a circular glass cutter will be more appropriate.
- Place the drilled piece on a level surface.
- Mark the circle that will be clipped.
- Place the glass cutter on the glass, and the suction cup will keep it in place.
- To dig a furrow, follow the circle you traced with the marker on the glass with the diamond of the glass cutter without stopping. Make sure to apply consistent pressure. You should hear the diamond shrieking against the glass. Similarly, you must mark the space between the suction cup and the initial circle with many circles to produce as many smaller and smaller grooves.
- Turn the glass upside down and remove the glass cutter. Then, touch lightly on the marked spot to lower the glass to the furrow of the smaller circle.
- Proceed in this manner from furrow to furrow until you reach the first.
- Remove the last remaining fragments with the section of the glass cutter intended for this purpose by levering.
- Lastly, clean the glass with sandpaper, being careful not to scratch the surface.
